Developed and delivered a focused feature for the SagerNet/gvisor repository, enabling the exposure of /proc/sys/kernel/pid_max within sandboxed environments by wiring it to kernel.TasksLimit. This approach addressed the risk of dependent process failures by ensuring that process limits inside sandboxes accurately reflect kernel constraints, thereby improving system stability and compatibility. The work required proficiency in Go, kernel development, and system programming, with careful attention to repository hygiene and maintainability. No major bugs were reported during this period, and the feature contributed to enhanced isolation, resilience, and predictability of process management across diverse sandboxed deployments.
